Manuscript Summary: Transcription of the works of Columbanus by Jodocus Metzler (1574–1639) of the Abbey of St. Gall: Instructiones I–XIII (pp. 1–58), Exhortatoria S. Columbani in conventu ad Fratres (pp. 58–60 ; Columbanus’ authorship is doubtful), Epistula IV (pp. 60–70), Epistula VI (= Instructio XIV) (pp. 70–72), De octo vitiis (pp. 73–74), Epistulae III, II, V, I (pp. 74–119). According to Metzler’s statement on p. 1, he copied a codex from Bobbio written in Irish script (ex manuscripto codice monasterii Bobiensis, litteris Hibernicis confecto) ; however, this codex has not survived until today. Metzler might have produced the copy in 1611 during a stay at Bobbio on one of his travels to Rome. This manuscript is the only textual witness for Columbanus’ letters I-V. It is conceivable that Metzler’s copy is based on the same codex as Patrick Fleming’s posthumously published (Collectanea sacra, Löwen 1667 ; in 1623, Fleming copied two manuscripts from Bobbio that have also been lost.)
